Just a quick question, just replaced fuel injector ( pig of a job first time round ), after removing to egr valve assembly from the end of inlet chamber to replace the vent hose as this broke near the valve cover, I noticed a fair amount of oil residue lining the inside of the inlet chamber.

I`m assuming if the blow by gas circulates that way, this has been drawn in from the valve covers second hose as the first hose goes down to the oil separator.

Hopefully someone could tell me if this right or not.

Thanks Paul
